While algorithms and artificial intelligence screen the portfolios, other programs make adjustments. In doing so, Nectar hopes to lower costs while improving performance – the holy grail in asset and wealth management. The Swiss fintech wants to compete with stellar returns achieved by major U.S. university endowments, for example.

To be sure, Appenzeller and Co still have to deliver on that promise, but the firm has carved out a new business area for itself.
